Dreadmaws ire or treasure cast issue
Rumbling rockslide for 6 at my 7/6, I was unable to sacrifice my treasure to cast dreadmaws ire. Unsure if its a treasure token issue, or a dreadmaws ire issue.

Rumbling Rockslide is a sorcery, so the spell was cast in a main phase. Dreadmaw's Ire has to target an ATTACKING creature, of which there are none in a main phase. So you do not have a legal target for your spell and thus can't cast it.
